2 SWPPP ANALYSIS AND DESIGN Design of the SWPPP Plan was completed in conformance with Volume II of the Drainage Manual. Compliance with the 12 elements is summarized below. Element 1: Preserve Vegetation / Mark Clearing Limits: Clearing limits have been delineated on sheet ER-01 of the construction plans. The clearing limits extend only to those areas that will be disturbed during construction of the subject project. The specific BMPs for marking the clearing limits that will be applied for this project include: • High Visibility Plastic Fence (BMP C103) Element 2: Establish Construction Access: The existing paved driveway will be utilized for a construction entrance. Due to the scope of the project, street sweeping is proposed to reduce/eliminate track-out from the site. If track-out becomes an issue, BMPS such as Wheel Wash (BMP C1O6) or shaker plates will be implemented. See sheet ER-01 of the construction plans for location. A detail is also attached on sheet ER-02 of the construction plans. The specific BMPs related to establishing construction access that will be used on this project include: • Wheel Wash (BMP C1O6) Element 3: Control Flow Rates: Due to the scope of the project, minimal changes to flow rates are expected. Temporary and permanent flow control measures are not proposed as part of this project. Element 4: Install Sediment Controls: Sediment control will be provided using Silt Fence (BMP C233) and Straw Wattles (BMP C235). The specific BMPs for sediment control that shall be used on this project include: • Silt Fence (BMP C233) October 2013 2-1 LDC Job No. 13-118
